suitable flash for landscape photography

19 October 2016 - 02:28 PM

* first post *

 

Hello all,

 

Hoping someone can please check my maths on this.

 

I'm new to guide numbers but not new to photography. But my only experience using my SB700 is about 4 years ago, I did some kitchen tabletop splashtography with my Camera Axe. B)

 

So, now I'm hoping to do something a bit more outdoorsy and photograph a waterfall and gorge near my house at night.

 

The subject distance is about 150 meters, and I'll be using F8.

 

So, (if I understand this correctly) GN = 150 x 8

 

or 1200m @ ISO 100.

 

Is this correct? Is there a flash available that has a GN this high?

 

Thank you.
